Surface my hidden assumptions

When the reasoning feels solid, which is usually when an assumption is buried in it.

Find the assumptions in my reasoning that I have not noticed I am making.

1. List every assumption you can detect, including the ones embedded in how I phrased the question rather than in the argument itself.
2. Sort them: stated explicitly, implied but not stated, and invisible to me.
3. For each, mark how load-bearing it is. If it were false, would my conclusion change, weaken, or survive?
4. Take the three most load-bearing and tell me how I could actually check each one, concretely.
5. Name the assumption that would be most embarrassing to have got wrong.

Do not list generic assumptions that apply to everything. I want the ones specific to what I have written.

My reasoning:

Assumptions and reasoning. Digging out what you are taking for granted, including the sunk cost you keep not naming.
